BU4812G-TR Product Details

BU4812G-TR Overview


This voltage supervisor has a total of 5 mounting terminals that can be used for mounting. There is a Tape & Reel (TR)-packaging method applied to IC management. In this IC power you will find 1 functions for you to refer to. It is possible to find on this power management a series of 1 channels. To assist you, this PMIC includes SC-74A, SOT-753 functions. There are a number of benefits that this PMIC has in common with other Simple Reset/Power-On Reset manage ics. When 2.4V is applied to the power ic, it conducts. During operation, the power ic is supplied with a voltage of 1. Surface Mount mounts power management on the wall. As a subcategory, this PMIC chip can be categorized as Power Management Circuits. In total, IC powers are 5 pins on the board. The pins of the power management system count 5. It is recommended that Vsup should not be less than 700mV for this IC power. Voltage (Vsup) shouldn't exceed 7V volts in this PMIC. Surface Mount is the recommended mounting type. The temperature of the supervisors should be set to this range: -40°C~125°C TA. While in operation, this supervisor has a voltage output of Open Drain or Open Collector. The power management's supply current is 550nA. You can always use BU4812, the base supervisor number, to search for similar PMICs of the manufacturer. If you want to work with PMIC chip, you will need to supply PMIC chip with a temperature at least of 880nA.
